I see a lot of comments here using the terms ZFS and Open ZFS interchangeably. But to my understanding, these are 2 different things. - ZFS is the very stable, non open source project that only works on BSD. - Open ZFS is an effort to rewrite ZFS in a totally open and free format that now runs on Linux. This was the idea I had, but I might be incorrect.

And to complement the other comments, the ZFS developers quit Oracle when it was made proprietary and moved on to work on OpenZFS, which has continued evolving. Talk by Bryan Cantrill https://www.youtube.com/watch?v=-zRN7XLCRhc https://www.youtube.com/watch?v=-zRN7XLCRhc 44:16 "[paraphrasing Bryan C.] I told Oracle management if they changed the license, the core ZFS would quit. And they lost all the ZFS team."

From my recollection, the basic story is Sun open sourced Solaris in the early 2000's (OpenSolaris). Today's OpenZFS codebase is an incarnation of the code released in OpenSolaris. It has since been ported to Linux and continues on as a separate thing from ZFS. Oracle has since "un-open sourced" Solaris, and is why ZFS and OpenZFS are different things today, although they both share a heritage.

Everything is OpenZFS now except Oracle's fork.

You're completely wrong. Open source ZFS wound up in FreeBSD (and from there, other BSDs) before Sun stopped releasing Solaris source. ZoL was a project based on said open Solaris source to run it on Linux, and while the Linux glue layer was not the FreeBSD glue layer, it was still based on the same ZFS source. OpenZFS switched from being based on the illumos codebase to being based on ZoL a couple years ago, merged in FreeBSD support, and FreeBSD 13+ ships based on OpenZFS and not the original ZFS port to FreeBSD. None of them are a new implementation.
